As best shown in Fig. 4,'the intermediate pinions 43 are carried by a swinging arm, the axis of which coincides with the axis of the shaft 40, the construction being such as to preserve operative engagement of the gearing when the combingwheol shaft is vertically adjusted, as hereinafter described. v

Ratchet segments 44 are pivoted at to the brackets 34, said segments having sockets 46 for the purpose presently described. Pawls 47 carried by a shaft 48, engage the ratchet se ments, said shaft having a handle 49 and an arm 50 to which one end of the spring 51 is connected so as to normally hold the shaft 48 and the pawls 47 in the position shown in Fig. 1.

The inclined table comprises a metal frame 52 with a middle supporting surface 53 usually of wood for the sake of lightness and has end rods 54 rcmovably fitting the sockets 46. Said table can be easily removed by slipping said rods out of said sockets, and its angle of inclination can be adjusted by grasping the handle as), moving the pawls 47 away from the ratchet segments in case it be desired to lower the table, and then releasreturn the pawls into holding engagement with the segments. Of course, f the .table is to be swung upwardly to a steeper angle of inclination, it is only necessary to lift the outer edge of the table, the teeth of the seg ment 41 riding over the pawls 47.

A pair of plates or brackets 55, adjustably secured to the table frame by clamps 56, support side guides 57 so that said guides can be set in. alinement with the guides 20. 4 A rod 58 is supported at its ends in brackets 34 and in turn supports collars or brackets 59 (see Figs. 2 and 5) said brackets carrying shoes 60 for the rubber retards v61. (See also Fig. 6). The collars or brackets 59 can be adjusted along the rod 58 and secured with the shoes 60 at any desired angle of inclination, by means of screws 62.

The inclined table is provided with frictiona-eclucing surface material. preferably of smooth metal such as tin. The large section 63 of the tin facing covers practically the entire area of the board 53. A strip 64 of the tin or similar material is adjustably held between members of thetable, as slmwn in Fig. 5. The lower edge of this tin strip 64 extends well under the combing-wheels, and covers all except the forward portions or tips of the rubber retarding strips 61. By means of adjusting screws 65 mounted in the brackets or collars 59 and extending up through apertures in theforward portions of the shoes (50, the tips of the friction retards 61 can be adjusted to compensate for combing wheels.

.wear or to vary the distance between their upper faces and the peripheriesof the combing rolls. If the covering or protecting strip 64 were not present, then when the pile of blanks is low, or, in other words, when there are a few blanks left on the table, their lower edges would contact with the retards and be prevented from being fed forward by the combing-wheels. The said strip 64 being adjustable or interchangeable with .other strips of different sizes, will provide for running through blanks of varying qualities of material, even down to the last one. strip .64: will be set farther back for heavy material than for light material, heavy material requiring a greater frictional retard, and also a heavier or stronger combingaction.

It is frequently desirable to change the elevation of the combing wheels, especially to compensate for wear of their rubber covered peripheries. provide the pivot rod 35 for the brackets 34, with eccentrics 66, said eccentrics being secured to the rod by screws 67. The brackets or arms 34 have hubs 68 mounted on said eccentrics 66. (See Figs. 8 and 9).

The

To effect this adjustment, 1.,

One end of the rod 35is srplared or otherwise formed to be engaged y a Wrench, 0.

portion of the'rod being screw-threaded to enable a. set nut 70 to be employed, said set nut cooperating with the frame 12 in which the rod 35 is mounted, to clamp the rod 35 and prevent it from rotating. By loosening .the nut and rotating the rod 35 audits eccentric 66 more or less, and then tightening up the nut 70, the brackets 34 may be adjusted so'that the shaft 40 and its combing-wheels 39 may be adjusted for the purpose hereinbefore descri ed. Of course, the pivoted catches 36 will readily permit of this adjustment without releasing thebrackets so that the frame might swing.

When the part-s are in the position indicated in Figs. 2 and 3 and. by full lines in Fig. 1, the pile or stack-of blanks will be placed upon the table, and the angle of inclination of the latter fixed so that the blankswill be caused to slide toward the The operator will, of course, so shape the pile or stack that the top blank will slide to position just beyond the extreme edge of the strip (34 to bear. against the uncovered portions'of the retards but soas to be combed off by the wheels 39,- the blanks belowv the top. one having their front edges at further points rezu'wardly. The drive of the combing rolls is positive through the gearing hereinafter described, but said combing wheels,

and also the table, may be quickly taken away from the position shown 1n Fig. '2 when it is desired tov feed from the bottom of a pile or stack placed on the belts 22.]
